To all whom it'rnay concern Be it known that I, GHARLEs E. MARTiN,

I a. citizen of the United States of America,

residing at Mansfield, in the county of Richland and State of Ohio, haveinvented certain new and useful Improvements in Roofs for Silos or theLike, of which the following is a specificatlon.

, terlocking them.

vation of the roof,

My invention relates to roofs for silos or the like.

The objects of my invention are to provide means of constructing a roofof tapered corrugated sections of sheet metal; to provide means oflooking all but one of the sections together, leaving a space to becovered by a single section without interlocking; to provide aventilator body' with an outwardly extending inclined flange to fit theouter surface of the roof or small ends of the tapered sections; toprovide a sleeve having an outwardly inclinedflange to conform with theinner surface of the roof on small ends of the tapered sections, andmeans whereby the flanged portions of the sleeve and ventilator can bedrawn tightly together with thesmall ends of the corrugated taperedsections interposed therebetween and rigidly held together. I obtainthese and other objects by the mechanism illustrated in the accompanyingdrawings in which Figure 1 shows a cross sectional side elepart of thesilo, and the ventilator. Fig. 2 shows an enlarged crosssectional sideelevation of the ventilator and method of attaching it to the vertex ofthe roof. Fig. 3 shows a side elevation of the silo with my roof appliedthereto showing a single tapered section attached to a ring and movablymounte upon the ventilator and adapted to bridge interlocked sections.Fig. 4 shows enlarged views of several tapered-sections showing themethod of interlocking them. Fig. 5 shows an enlarged view of themoVabIe ring and one tapered section which .is pivotally attached to thering and adapted to bridge the space left open by interlocked sections.Fig. 6 is an enlarged view of part oftwo tapered sections showing themethod of in- In the drawings, reference numeral 1 represents a silo orthe like which can be-made of any form desired. Upright supports 2 areattached to the inner periphery of the the space between the 18 arerigidly known fastening means, and the free ends are bent to conform tothe angle of the roof that it is desired to make and are attached to theunder surface of the roof by the rivets a. A

series of corrugated tapered sections 3 are 7 provided to form the roofand locked or united together to forma conical shape as shown. In orderto securely interlock these tapered sections together, the end 4 of onesection is bent up at an angle as shown in Flg. 6, and the adjoiningedge of the oppoloop and bent in the opposite direction to form an openloop as shown at 5 and '6 forming a space 7 into which the end 4 1sinserted as shown in Fig. 4 and then forced up until it is made flushwith its companion sections. It will be observed that the edge 8 of thelooped slat is also turned at an angle which coincides with the angle ofthe end 4 of the opthe tapered corrugated sections of the roof togetherprovides an efficient means of uniting the sections together andeffectually prevents rain or the like from working its way into the silowithout the necessity of soldersite tapered section is bent to form aclosed 'posite slat. This method of interlocking ing the sectionstogether. In order to further secure the sections together, athroughgoing bolt 9 is fitted to apertures 10 formed in the adjoiningsections and the nut 11.

threadably engages the bolt 9 and when tightened serves as additionalfastening means. It will be observed that each slat is provided on oneedge with a bent end as shown at 4 and its opposite edge folded orlooped twice to form the space 7 for the engagement of the end. 4. Allof the tapered sections are interlocked in this manner to form theconical shaped roof 12 as shown except an pening 13, equal thedimensions of one section, is left.

A ventilator 14 having a flanged portion 15 is provided to fit overandextend down wardly upon the outer surface of the small ends of thetapered sections. A sleeve 16 having a flange 17 is inserted within theinner periphery of the ventilator and forced downwardly until thetapered flange 17 of the sleeve contacts with the inner surface of thesmall ends of the tapered sections leaving the ends of said sectionsinterposed. between the fiange 15 of the ventilator and the flange. 17of the sleeve. L shaped brackets fastened to the sleeve by rivets 19,the heads of which areflush with y the outer periphery thereofto permitadjustment of the sleeve within the inner periphery of the ventilatorfor clamping purposes. Standards 20 are attached to the inner peripheryof the ventilator by rivets 21 and the lower ends of the standards 20are bent L shape to aline with the ends of the brackets 18 and both havealined apertures into which a through-going bolt 22 is inserted ,which anut 23 threadably engages and when tightened draws the sleeve 16 in anupward direction in contact with the inner surface of the" roof,securely clamping together the interposed small ends of the taperedsections which form the roof. The standards 20 support a hood 24 whichis fastened to the standards by rivets 25.

In order to complete the roof and cover up the opening 13, I provide aring 26 having a bifurcated portion 27 and pivotally attach a taperedcorrugated section 28 thereto. The pivoted connection permits thetapered section 28 to be raised from the position shown in Fig. 3 andthe movable ring permits the tapered section to be moved laterally untilit is directly over the opening 13, overlapping the edges 29 and 30 ofthe interlocked corrugated tapered sections and thereby covering theopening 13. In order to hold the single section 28 securely in place, abolt 31 is provided which passes'through apertures in the bifurcatedportion 27 of the ring and when drawn up by the nut 31 securely clampsby friction the ring and its attached section to the ventilator.

It will thus be seen that a very efiicient roof is obtained and any partcan be replaced without affecting any other part of the roof and it canbe assembled or taken apart without difliculty. It will further beobserved that the roof can be shipped from the factory in a compactform.

What I claim is 1. In a roof for silos and the like, a series of taperedsect-ions longitudinally corrugated, one side-of each section being bentover upon itself to form a closed loop and being further bent to form anopen loop that underlies the closed loop, said side of said sectionbeing extended beyond the outer side of the closed loop and being bentupwardly to engage the adjacent side of the adjacent section, saidadjacent side of the adjacent section projecting in the open loop, thelooped and the extended portion of the one sheet forming the two wallsof. the final corrugation of that edge of the sheet and being engaged bythe two walls of the final corrugation at the complemental edge of theadj acent sheet and fastenmg means passing through said side of theadjacent section and the upwardly bent side portion of the firstmentioned section.

' 2. AIoof for silos, comprising a series of corrugated and taperedinterlocking sheet metal sections, a sleeve having an outwardly anddownwardly extending flange to support the small ends of said sections,a spring clamp carrying a non-interlocking section rotatably mounted onsaid sleeve so as to permit said non-interlocking section to swing in alateral direction.

3. A roof for silos, comprising a series of corrugated and taperedinterlocking sheet metal sections leaving an opening, a sleeve providedwith a flange on its lower portion adapted to support the small ends ofsaid sections, a second sleeve having an outwardly and downwardlyextending flange formed on its lower portion and adapted to fit andextend over the small ends of said sections, means to movably connectthe sleeves together the second sleeve having an annular groove formedthereon, a spring clamp carrying a non-interlocking section rotat-ablymounted in said annular groove so as to permit said non-interlockingsection to swing over the opening left between said sections and awayfrom said opening as described and set forth.

4. In a self-supporting roof, the combination of a series ofinterlocking corrugated and tapered sheet metal sections arranged toform a cone shaped roof leaving an opening in the center, a sleeveprovided with a flange on its lower portion adapted to support the smallends of the section's, means to fasten said small ends to said sleeve,inwardly projecting brackets secured on the inner periphery of saidsleeve, a second sleeve provided with a flange and fitted to extend overthe outer periphery of said sections, and means engaging said bracket todraw said sleeves together whereby the interposed small ends of thesectionsare clamped together, substantially as described and set forth.

5. A roof for silos, comprising a series of interlocking and corrugatedtapered sheet metal sections, and one movable section, a sleeve adaptedto support. the small ends of said sections provided with an annularflange to fit the inner surface of the small ends of the taperedsections, a second sleeve having an outwardly and downwardly extendingflange fitted to the outer periphery of said sleeve and adapted toextend over the small ends of said tapered sections leaving the smallends of said sections interposed between the outwardly extending flangeof the sleeve and the outwardly extending flange of the second sleeve,and means to connect both sleeves together and bind said small ends ofthe sections therebetween to form a self-supporting roof.

6. A roof for silos, comprising a series of interlocking and corrugatedtapered sheet metal sections, a sleeve adapted to support the small endsof said sections provided with an annular flange to fit the innersurface of the small ends of the tapered sections, a sec- 0nd sleevehaving an outwardly and downwardly extending flange fitted to the outerperiphery of said second sleeve and adapted to extend over the smallends of said tapered sections leaving the small ends of said sectionsinterposed between the outwardly extending flange of the first sleeveand the out Wardly extending flange of the second sleeve, means toconnect both sleeves together and bind said small ends of the sectionstherebetween to form a self-supporting roof, and a cap carried by thesecond sleeve.
